Granny Square Cardigan Pattern

Easy Granny Square Cardigan Pattern

We couldn’t close out Granny Month without sharing one more showstopping project – Meet: THE Granny Square Cardigan.

We sat down as a team and chatted through all of the details that would make the perfect granny garment, and made it happen! Loaded with tips to customize the pattern for your perfect fit, you can turn colorful granny squares into a literal technicolor dreamcoat.

Our granny square cardigan pattern & yarn bundles for sizes S – 3XL are available for purchase in the TNTP shop!

Granny Square Cardigan Colors

Currently experiencing color decision paralysis? We’ve curated four different yarn bundles that will stitch together beautifully!

Granny Square Cardigan Sizing

Our cardigan pattern & bundles are available in three sizes:

  • Size 1: ~15″ back width
  • Size 2: ~20″ back width
  • Size 3: ~25″ back width

This measurement is taken across the row of squares where the back panel meets the armhole seam. If you’re unsure what size to go with, try measuring a well-fitting garment you already own for reference!

We’ve also included tips in the pattern on how to decrease/increase this width by adjusting the rows of your squares if you’d like to it to fall somewhere in between the suggested sizes.

Colorful Crochet Supplies


Here’s a list of everything you’ll need to crochet your own cardigan:

*The total amount of yarn you’ll need in each color can vary, depending on the number of colors you’re using, the size of the cardigan you’re making, and the desired length of the cardigan (ex. cropped vs midi length as pictured).

You can find our guidance for yarn quantities for this project in the description here.

Making a granny square cardigan can be intimidating, but I can assure you that the most difficult part is actually finishing the squares. After that, the garment stitches together in no time! If you reach a roadblock (or just need the final push to finish those squares) your new best craft friends are here to cheer you on!

    Hi, I’ve been obsessed with this pattern for a while and finally ready to go for it! I’m just not sure which size to make and want to make sure I order the right bundle. I recently made my first sweater and it turned out HUGE and don’t want to make that mistake again. I think I’m measuring about 15” across the back, so a size 1, but I’m currently an XL in most women’s clothing so I feel like that can’t be right. Any tips?

      Hi April! I’m so happy you’re taking on the cardigan pattern! It really is such a beautiful piece, and well worth the love that goes into it. <3
      Based on that measurement, it does sound like Size 1 would fit your needs. It's hard to say exactly, as everyone's tension when crocheting is different, so if your stitches are tighter/looser, your squares might be a slightly different size. The good news is that the pattern includes loads of instruction on how to tweak the design to fit you perfectly. For example, you may find that adding another round to each of the squares gives you a width you're happier with, or adding another entire row of squares to the back panel, etc.

      Once you have a few squares made, we recommend lining them up across the back of well-fitting sweater to give you an idea if your sizing direction is on track (keeping in mind that the join method will add a bit of width as well). I hope that's helpful! You can always shoot an email over to if you have any further questions/run into any trouble throughout the process!

    Hi I’d love to make this. I have a huge stash of double knit. Will that be ok for this please ?
    Many thanks
